Joplin is an open source note-taking and to-do application that organises notes and lists into notebooks. Prior to 3.7.7, Joplin Server's ItemModel.checkIfAllowed() authorizes writes to items with a share ID when any share_users row exists for the caller, without requiring ShareUserStatus.Accepted. A low-privileged authenticated user with a pending folder-share invitation can create an item under the share ID, and ShareModel.updateSharedItems3() propagates the injected content to the owner and accepted participants before the attacker accepts the invitation. This issue is fixed in version 3.7.7.
